This book is an undergraduate textbook for students of electrical and electronic engineering. It is written at an intermediate level, with second year students particularly in mind, and discusses analogue circuits used in various fields. Basic electronics has been omitted so that appropriate emphasis can be given to the design of the most popular and useful circuits. The contents of chapters 3, 5, 7 and 8 are not covered together by any other single textbook available on the market. Each chapter also contains a significant number of worked examples and several carefully chosen problems at various levels of difficulty. Each topic has been carefully selected, and the author concentrates on the practical details and applications of the material he covers. Both students and practising engineers alike will therefore find this book extremely useful and informative.
